Topics covered in this Capacitor Class 12 lecture by ABJ sir IITD with timestamp:

00:00 18:35 Motivational speech by ABJ sir: To make a feel of offline classes at the Online platform, ABJ sir tried to motivate students.
18:45 30:46 Charging of Capacitor: Charging the capacitor stores energy in the electric field between the capacitor plates. ABJ sir explained this concept using a diagram and KVL/KCL. ABJ sir derived the formula of Charge on the capacitor at t=0, any time t or steady state. He also explained a new term, TIME CONSTANT.
30:47 36:40 Charging of Capacitor: Curve of charge on capacitor wrt time: ABJ sir draw the curve b/w charge on capacitor and time. With the help of this graph, he also explained the charge at t= Time constant equal to 0.63 times the maximum charge on it & charge at transient state.
37:02 42:45 Charging of Capacitor: Important points Formulae of Current at any time t across the capacitor, Curve of current across capacitor wrt time and value at current at time constant.
43:00 52:21 Rate of heat dissipating by resistance during charging of capacitor: Formulae of heat dissipated rate is derived by ABJ sir using the relationship of power , current and resistance. Also curve b/w Power & time is drawn by ABJ sir. Formula of heat loss by resistance also derived.
52:21 01:05:27 Rate of storing electric energy by Capacitor: Rate of energy store is known as Power, and power of the capacitor can be derived using the formulae of power P=VI , where V Voltage & I Current. ABJ sir also find the value of time, at which Power is maximum and value of maximum power. ABJ sir also draw curve b/w power & time, also using the area of curve ABJ sir verified the formulae of energy stored.
01:06:06 01:11:59 Capacitor Problem 1: Based on the Charging of the Capacitor. In this problem, we have an RC circuit with R = 1000 ohms, C = 100 micro Farad, & Voltage of battery V = 100 V. At time t=0, Switch is turned ON. So we have to find the value of different parameters at time t.
1. Current in the circuit 3. Voltage across Resistor
2. Charge on the capacitor 4. Voltage across Capacitor
01:12:29 01:22:57 Capacitor Problem 2: Based on the Charging of the Capacitor. In this problem, we have an arrangement of Resistors and Capacitors connected with a battery. We have to find charge on capacitor at any time t. To solve this problem, ABJ sir used KVL and by solving equations & Using integration, value of charge on the capacitor is determined.
01:22:57 01:28:10 Capacitor Problem 2: (Using Trick) Based on the Charging of the Capacitor. In this problem, we have an arrangement of Resistors and Capacitors, connected with a battery. We have to find charge on capacitor at any time t.
01:28:10 01:33:18 Capacitor Problem 3: (Using Trick) Based on the Charging of the Capacitor. In this problem, we have an arrangement of Resistors and Capacitors, connected with a battery. We have to find charge on capacitor at any time t.
